Abstract
THE Spacelab Scientific (CPSE) Airlock is equipped with an experiment table to transfer experiments from the Module into space environment. In the table drive system multi‐stranded steel cable is used, running over small‐diameter pulleys. For cleanliness requirements the original cable lubricant was replaced by a fluorinated fluid. Cable cleaning and relubrication methods have been established. The coating thickness can be chosen. Tests were run with and without lubrication. The cables were tested at ESTL on a test rig, based upon the experiment table design, in a thermal vacuum test. The performance has been improved by: • a more flexible cable • increase of lubricant thickness • decrease of contact stresses Testing in air has been included as it appeared to be an aggressive environment, where a failure occurred.

Abstract
Purpose
The purpose of this paper is to examine the role of the European Novel Food Regulation (ENFR) on consumers’ acceptance of and willingness to pay (WTP) for radical food innovations. The research question is focussed on determining whether the ENFR is hampering the market potential of insect-based food products in the European Union (EU). The authors position this question within the domain of regulatory barriers related to food innovations.
Design/methodology/approach
Using a choice experiment, the authors assess the presence and relevance of these failures through the analysis of consumers’ acceptance and WTP for insect-based food products with different product attributes directly imposed by the ENFR. Namely, the authors assess the effect of the visualization of insects in the product, the use of logo, and nutritional information.
Findings
The results show that consumers prefer and are willing to pay a premium price for insect-based products with a nutritional health claim and logo, but they are not willing to pay for a product with a visualized insect.
Originality/value
This paper highlights the risk of regulatory failures for novel foods in the EU, such as insect-based food products due to the ENFR.

Abstract
The objective of this chapter is to provide an approach to the farmland abandonment problem in Galicia, the Spain’s north-western region. We describe the land use pattern that characterized the traditional agricultural system, and analyze the process of structural adjustment and changes in land use recorded in the last 50 years. The empirical basis is provided mainly by an original elaboration of agricultural census data for the period 1982–2009. The results show that in the last five decades the area devoted to crops and pastures was constrained to a small portion of the territory (just over 20%), while the agro-livestock uses of hill land which were very important up to the mid-twentieth century disappeared. All this led to a remarkable expansion of abandoned land, which currently occupies at least 20% of the regional area. The drivers of this farmland abandonment are diverse and vary from one zone to another. But among them the conditioners derived from the structure of land ownership must be emphasized, coupled with the poor functioning of the land market and leasing. Land abandonment has had a major impact on the dynamics of the agricultural sector, limiting the size of farms and causing an increasing intensification in a small portion of the territory. This has also led to severe environmental problems, especially forest fires. Consequently, improving mobility and land use should be a priority of agricultural and rural development policies in this region.

Abstract
Purpose
This paper aims to present some “natural philosophy” that may be associated with multivibrator. The motivation is given by the exposition work (Mathis, 2019) of Wolfgang Mathis.
Design/methodology/approach
Considering the multivibrator’s states as a realization of Boolean Logic, the author discusses the logical basics in the scope of physical realization, and Brouwer’s concern regarding the “tertium non datur” principle.
Findings
A mechanical multivibrator with Coulomb friction is treated to enrich the standard set of the traditional examples. The associated energy analysis lies on the border of Newton’s and Lagrangian’s mechanics.
Research limitations/implications
It is the author’s own work. The author is limited by his modest abilities, given to him by the Great Lord.
Practical implications
Teaching and improving engineering understanding of the oscillatory systems.
Originality/value
Together with Mathis (2019), the present paper outlines the topic of multivibrator as a field having significant heuristic and pedagogical value.

Abstract
Adopting an EU policy lens, this chapter primarily addresses the proposed pivotal role of firm-level innovation capability (FLIC) in small and medium-sized enterprises (SMEs) as a stimulant of sustainable development (SD) and green growth in Ireland/Wales. The chapter specifically examines the scale and scope of the green economy (GE), and considers the importance of organizational inherent “green” innovation capabilities (GICs) to achieve it. Underpinning the study is the methodology and concept of utilizing a facilitated cross-border multi-stakeholder learning network to enable knowledge transfer and exchange practices to flourish between partners, acting as a significant predictor of the development of SME GICs structures. Specifically, against the backdrop of the Green Innovation and Future Technologies (“GIFT” hereafter) INTERREG 4A Project, the research assesses how academic–industry partner exchange and inter-group learning and cooperation facilitates the development of GICs in smaller enterprises to realize a sustainable smart green economy in Ireland.
